We are glad to introduce you our Company, the products and services that we can offer you.

AMT is ISO 9002 certified since 1998 and obtained the ISO 9001:2008 certification in March 2010.

Since 1980 AMT we supplied mechanical tubing to original equipment and component manufacturers. Our core business is the supply of “custom made” carbon and alloy precision steel tubing suitable for the manufacturing of mechanical parts and elements.

AMT sells directly in Italy and operates both directly or through distributors, agents or associated partners in the rest of Europe.

AMT supplies its tubings in electric resistance welded or hot rolled seamless conditions: these tubes may be supplied as cold drawn, heat treated, machined or as a finished component manufactured to the customer’s specification.

AMT seamless and electric resistance welded mechanical steel tubing comes in a wide range of carbon, alloy and stainless steels. Precision cold drawn tubes are finished to tolerances of hundreds of millimeter and smoothness similar to that of fine machining.

AMT custom made precision steel tubing is used in the manufacturing of plain and spline hollow shafts, diesel engine rocker shafts, plain and splined sleeves and couplings, threaded rings, gears, power take-offs, cylinder body and piston rod for shock absorbers and hydraulic cylinders, safety and breaking parts for cars, trucks, tractors and motorcycles and go-kart and motorcycle chassis.

AMT sales range include also mechanical components, always manufactured according to specific customer drawings, that may be supplied as finished and tested parts for final assemblies or as pre-machined and heat treated parts ready for further processing.

AMT carries permanent inventories of KART tubes:

• Seamless cold drawn tubes in 25CrMo4 steel for go-kart chassis and rollbar

• Welded and welded cold drawn carbon steel tubes for go-kart axels and all go-kart components

AMT has specialties with short delivery terms as:

• LARCO: hard chrome plated carbon and alloy engineered steel bars, precision finished to tolerance ISO f7 in sizes over 130 mm OD that, when cut to length, are ideal for the manufacture of hydraulic cylinder piston rams and hydraulic press columns.

• TUBCROM: outside hard chrome plated carbon and alloy steel tubes eventually honed or skived and roller burnished inside to H8

• LEVINOX: stainless steel tubes inside honed to H8-H11 suitable to manufacture pneumatic and oleo-hydraulic cylinders to be used in case of severe corrosion conditions

• ROLLERS: ultra fine straightened tubing and shafts suitable to manufacture high speed tubular rollers and shafts

AMT stands behind the quality of its products and services. You can depend on AMT to get the precision steel tubing, chrome plated bar and related components required, without the need to deal with multiple suppliers. Choosing AMT products and services means to save purchasing time and money as the company business is the customer satisfaction. Technical and sale AMT staff is at your complete disposal for any quote or further information you might need.
